is there a way i can delete "bang ya beats on" and the 15 other shit samples and replace them with something more usable? id like to have 808 sounds there so i have them no matter what card im using

4 sure, man! just look up the manual!!!

i read that thing religiously, i just couldnt find the part about disabling the protection

Here’s how to erase all of the internal memory (bank A and
B) sample and pattern data, as well as the effect memory
settings, and initialize other internal settings to the default
state.
This operation will cause all internal memory data to be lost. If
necessary, you should make a backup before you proceed.
(
“Saving backup data (backup save)”
(p. 48))
1.
While holding down [CANCEL], turn on the power of
the SP-555; this will turn off the internal memory
protect setting.
The display will indicate “P.oF,” indicating that
protection has been disabled for the samples and pads
of banks A–J.
2.
Switch off the SP-555’s power.
3.
While holding down [CANCEL], [REMAIN], and [DEL],
turn on the power.
The display will indicate “ini,” and [SAMPLING] will
blink.
If you decide to cancel the operation, simply turn off the
power.
4.
If you are sure you want to initialize the SP-555, press
[SAMPLING].
[SAMPLING] will light, and the dot in the display will
blink. When the blinking dot disappears, the operation
has been completed.
Never turn off the power while the dot is blinking. Doing so
may destroy the data.

Thanks! I don't know what i would do if i heard "bang ya beat on" again.
